Temple Konzo -ji 金倉寺 is the 76th Sacred Temple of Shikoku, where Chisho was born, a nephew of Kobo Daishi. At 39, he traveled to China to learn more about Esoteric Buddhism, in the footsteps of Kukai, Saicho and Dengyo Daishi. He returned five years later with numerous volumes of scriptures. At age 54, he became the 5th abbot (Zasu) of temple Enryaku-ji at Hieizan, the headquarters of the Tendai sect.

Here are two illustrations from the illustrated cards for a performance about the life of this priest.

Here is the story abbreviated:

As a boy, his name was Hiro 広雄. He was intelligent and studious and all called him "Wisdom Child" 智慧童子. At age 15, after reading most of the Chinese classics and treatiese, he decided to become a priest.
He went to Mount Hiezan to study and took the name of Enchin 圓珍.
He dilligently studied the scriptures for many years.

One day when he was performing his duties, the Buddhist Deities rewarded his work and he saw a Golden Fudo Myo-O emerge from the flames of his fire altar.

Fudo Myo-O appearing in the Flames talked to him:

"I have seen you study so dilligently, I am deeply impressed with your ambitions.
I am sure you will carry on your ascetic practices dilligently. Think of the difficulties in your mind morning and evening and carry sacred water for me."

Fudo Myo-O statue.Chisho decided during his 22 year long religious training at Mount Hiei (Kagoyama Shugyo), to devote his life to Fudo Myoo (the “Unmovable King of Wisdom”, Buddhist deity). Still today, an image of Fudo Myoo (national treasure, normally withheld from the public) is enshrined in the Mii-dera temple..http://darumamuseumgallery.blogspot.jp/2007/06/mii-temple.html.
